Hex is an undead elven sorceress in Skylanders: Spyro's Adventure. Hex is a light blue-skinned, slender and slightly tall figure, aided by her constant levitation and using magical purple mist. The elf wears a black headress that goes around her entire head, covering her short black hair(as seen with Hallow's Eve Hex) and tiny ears; the headdress is composed of three flat hornlike sections on each side, the highest one having two tips. Her eyes are a featureless light blue(sometimes depicted as milky white), and notably she has a large forehead.
She wears a sleeveless black dress with a large collar, with many dark gray lines dividing sections of it and converging at the chest in the shape of an ankh. Hex also wears a pair of black shoulder pads pointing upwards and gauntlets, which have dark gray spirals along the forearm and dots on the back of the hand. Though rarely visible, she also wears black boots, which as seen with her LightCore's red reflections, have ripple shaped soles. Since her Undead transformation, Hex has become spooky, mysterious, and even sinister, striking fear into the hearts of her enemies. She has also developed a fondness for skulls. It has been said that Hex has laughed only once since her transformation -- apparently at an incident involving Trigger Happy, Slam Bam, and a gold coin in the rear end. She also has a tendency to act on her own, even if it means not sharing her plans with her allies. Strangely, in Skylanders: Battlecast, Hex appears more prideful in battle, as well as sounding more cynical, and like other Skylanders in it, will scold and sneer at the Battlecaster should they harass her by poking. Long ago, Hex was a gifted and powerful sorceress who traveled deep into the underworld to confront the Undead Dragon King named Malefor, who made several attempts to capture her to learn her secrets. Though she successfully battled the dragon, Hex returned from the underworld changed – having unwillingly joined the ranks of the Undead. Many are wary of her since her transformation, suspecting she has used her powerful magic for evil purposes. But Eon trusts her, and views her as a valuable Skylander ally.
